Sheet metal bends from an internal cut-out

Sheet metal bends from an internal cut-out

Sheet metal bends from an internal cut-out

(OP)
I am trying to create a sheet metal model of a part with flanges formed from a rectangular cut-out in the center of the part. The corners of the flanges are 45 degrees.

If I use an edge flange, I can only do opposite sides of the rectangle. When the other flanges are added, SolidWorks can't unfold it, because the corners interfere.

When I try adding sketched bends, SW says it csn't figure out the geometry.

I've tried adding them as extrusions, but SW won't convert them to bends.

Try putting in all bend reliefs before putting in the flanges.

RE: Sheet metal bends from an internal cut-out

Use the edge flange tool, but edit the sketch by chamfering the corners of the flange.  It will unfold if you remove the corners.

RE: Sheet metal bends from an internal cut-out

You should be using the Mitre Flange feature.

RE: Sheet metal bends from an internal cut-out

Cor,
The miter flange only works around bent corners, like a box made from a strip of material.  The miter flange will start at one end of the strip and miter the corners in the areas where the corner of the box is.

It sounds like huey1d has a flat part with a square cutout in it.  The miter flange in this situation will create flanges but it will not automatically 45 the corners.  The edge flange and editing the sketch is the way to go.

Shaggy18VW ... I'm using SW2004 & it works OK for me! I do have to chamfer the corners, but the basic function is fine.

I guess it comes down to personal preference. Using the Edge Flange involves 4 features (one flange for each side). Using the Mitre Flange involves 2 (flange plus chamfer).

RE: Sheet metal bends from an internal cut-out

(OP)
I tried the miter flange. Got a message "The sketch is not suitable for the miter flange. Am trying the Edge flange. Will let you know if it works.

RE: Sheet metal bends from an internal cut-out

If you are getting that message, you are probably picking the wrong face or edge to start from.

Or

You have a strange edge style on your your SM part.
